LASer:INC	FRONT PANEL

The LASer:INC command increments the selected laser control mode setpoint by one or more steps. Optional parameters allow multiple steps to be incremented and the time (in ms) between increments to be set, respectively. This is an overlapped command. Other commands may be executed while this function is in progress.

Parameters	0, 1, or 2. The first optional parameter is the number of steps, and the second optional
	parameter is the number of ms between steps.
Notes	The decremental default amount is one step. The step size can be edited via the
	LAS:STEP command. LDX-3232 default values are 0.1 mA, 0.1 mW, or 1 µA.
	If the first optional parameter is used, but not the second, the LASER setpoint is
	incremented by a multiple of the LAS:STEP size without changing the LAS:STEP size.
	The second optional parameter is the time, in ms, between steps.
	If both optional parameters are used, the user may create an automated stepping ramp
	function for the LASER output.
	If the first optional parameter is entered as zero, “LAS:INC 0”, the command will do
	nothing.
	The minimum time to complete one increment is about 20 ms. Therefore, values for the
	second optional parameter (time between increments) have a practical minimum of 20.
	This command should not be overlapped with “LAS:DEC” or other “LAS:INC” commands.
Examples	“LAS:MODE:I; LAS:STEP 3; LAS:INC” -action: The laser source current setpoint is
	incremented by 0.03 mA.
	“LAS:MODE:I; LAS:STEP 3; LAS:INC 3” -action: The laser source current setpoint is
	incremented by three times the amount described in the first example.
	“LAS:MODE:I; LAS:STEP 3; LAS:INC 3,5000” -action: The laser source current setpoint
	is incremented by the amount described in the first example, three times, with
	fiveseconds between incremental steps.
	“LAS:STEP 1; LAS:Mode:P; Las:INC” -action: The power setpoint is incremented by
	0.01 mW.
